Nexperia USA Inc. 74LVC1G74DC/S470,1

Overview

74LVC1G74DC/S470,1 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, and IOFF partial power-down support. It functions as a synchronous storage element in clock-domain interfacing, level translation, and metastability-hardened control paths in mixed-voltage digital systems.

For engineers reviewing the 74LVC1G74DC/S470,1 datasheet, 74LVC1G74DC/S470,1 pinout, 74LVC1G74DC/S470,1 application, or 74LVC1G74DC/S470,1 equivalent, this page delivers verified functional behavior, validated VSSOP8 pin mapping, confirmed timing parameters (tpd ≤ 4.1 ns @ 5 V), and real-world use cases in voltage-level translation and edge-sensitive state capture - all derived from Nexperia's Rev. 18 product data sheet.

Technical Context

This device implements a master-slave D flip-flop architecture with asynchronous active-low set and reset, enabling immediate state override independent of clock. Its Schmitt-trigger inputs tolerate slow-rising signals, and IOFF circuitry disables outputs during power-down to prevent backflow current when VCC = 0 V.

It supports dual-supply interoperability: inputs accept up to 5.5 V regardless of VCC (1.65–5.5 V), allowing direct interface between 3.3 V logic and 5 V peripherals. Propagation delays scale predictably with supply voltage - tpd = 4.1 ns max at 4.5–5.5 V, 5.9 ns at 3.0–3.6 V - and setup/hold times remain stable across temperature (−40 °C to +125 °C).

FAQ

What is the maximum clock frequency supported by the 74LVC1G74DC/S470,1?

The device supports up to 200 MHz maximum clock frequency at VCC = 4.5–5.5 V, as specified in Table 9 of the datasheet. At lower voltages - e.g., 3.0–3.6 V - fmax drops to 175 MHz. This rating assumes proper signal integrity, load capacitance ≤ 50 pF, and ambient temperature within −40 °C to +125 °C.

Does the 74LVC1G74DC/S470,1 support 5 V-tolerant inputs when powered from 1.8 V?

Yes. All inputs (CP, D, SD, RD) are overvoltage tolerant to 5.5 V regardless of VCC, per Section 2 and Table 6. This allows direct connection to 5 V microcontrollers or sensors while the device operates from a 1.8 V rail - a key feature for voltage translation without external components.

How does the IOFF function behave during power-down?

When VCC = 0 V, the IOFF circuitry disables both Q and Q̅ outputs, limiting leakage current to ±2 μA (Table 8). This prevents backflow current from live system buses into the unpowered device - critical for hot-swap compliance and preventing damage in modular power architectures.

Can the 74LVC1G74DC/S470,1 be used in place of a 74LVC2G74 dual flip-flop?

No. The 74LVC1G74DC/S470,1 contains only one D-type flip-flop, whereas the 74LVC2G74 integrates two independent channels in one package. Substitution would require doubling the footprint and routing - and forfeit benefits like shared control lines or compact dual-channel synchronization.
